    Poor man Mode C Install

    I'm doing a poor man's Mode C install thanks to all of the units popping up on ebay from ads-B replacements. I just want a quick reality check here to make sure there is nothing I am missing. I think I cna get everything I need for under $300 plus whatever the radio shop charges to sign it off...

    Delorean Aerospace

    Side note - I find it odd that they have N417TR prominently displayed in the picture but they don't have it reserved. I applaud all of the creativity with these kinds of designs but I'm suspect of any company that claims to make "an aircraft for the masses". As long as there are humans...

    Oshkosh 2017

    I'm going to be making my maiden voyage with the amphib this year. This will be my 3rd year flying in but first in the airplane I built. I will be there all week so I will definitely make it out for breakfast at least one morning. I can't freaking wait, best week of the year every year. I'm...

    How do I know if a Transponder is compatible with ADS-B

    Not to pick on you but I would really appreciate it if people would support these kinds of claims with FAR's. There is no reason to speculate on this stuff. The FAR's are readily available and are clear and concise. I have never seen what you are saying anywhere in a FAR or in any type of news...

    How do I know if a Transponder is compatible with ADS-B

    http://rgl.faa.gov/Regulatory_and_Guidance_Library/rgFar.nsf/FARSBySectLookup/91.215 See Link above. I don't believe that is a true statement unless I am reading something wrong. You need a transponder to fly in class E above 10,000 feet, otherwise its just A, B, C and the mode C veil. This...

    How do I know if a Transponder is compatible with ADS-B

    I don't even know if that is the right way to ask this question or not but here is what I am looking to do. I have two airplanes and neither have transponders. First plane is an Aventura 2 Amphib. This obviously isn't a cross country machine and I don't fly into any airspace where a...

    Can I paint a composite plaine a silver / grey color?

    Great info gentleman, that is kind of what i suspected. Makes my decision easy! Marc -Cool, chart and infromation - very infromative! I noticed you live in Tehachapi - that was where I picked up the engine (o-235) for my amphib this past winter. It was from a retired A&P who lived up in the...

    Can I paint a composite plaine a silver / grey color?

    I recently purchased a flying quickie Q200 from a local pilot/builder/owner. It needs a fresh coat of paint and originally I was thinking stick with the white but my paint guy (who is also a pilot) said that silver / grey would be comparable to white as far as reflecting light / heat. We all...

    How much height do floats add to a plane?

    Not much to add of any value other than for posterity but keep in mind this will be a different story if it is a taildragger going on amphibious floats. Also this would be harder to do with a float plane but there are option if your hangar door is too low. You can make a trench for the gear to...

    Cable Operated Fuel Shutoff Valve Ideas PLEASE!!!

    I did exactly what you are looking to do with a bowden cable and brass ball valve. I built a mounting bracket for the cable out of a bent piece of aluminum and used adel clamps to attach it to the ball valve. I Used .020" safety wire to attach the bowden cable sheath to that bracket. I made a...

    Static Testing a Wing

    Bill - It is possible the the load was slightly aft. I guess I could recalculate it based on where it was actually loaded. I wondered the same thing from the video (had the shear web already started to buckle but I can't tell of it is an optical illusion or if it really had. That was my exact...

    Static Testing a Wing

    Thanks - we got lucky with our camera placements! It is cable braced. The cable is attached 123" out and the span is 178". I never studied this much but I thought all along that the cable was attached too far out and I think it was. It created a high compressive loads in the spars. What I saw...

    Static Testing a Wing

    ^Well I am sure that by now you know that yes - I (Matthew) am from Toledo, Ohio and the wing in question is the same one our mutual friend, Andy, has been working on. I didn't take any pictures but we had several cameras rolling and there will be a good video made of the failure. For now we...

    Static Testing a Wing

    Great news - I found a three view of it. So, I'm figuring on the forward spar and wires carrying all of the lift but here is the thing that you can see from this drawing, with the chord at a 0° angle of incidence if you were to plot an x y axis at the aft spars attach point, with X being in the...

    Static Testing a Wing

    ^Interesting, I will have to re-look at this (shrenck loading) it did not make sense when I read it but it seemed pretty clear at the time what the publication I was reading said. Our deflection calculation give 4" of deflection - I think we will be safe with the 6" but well see. Your...

    Static Testing a Wing

    Thanks for all of the good feedback people! We mounted the wing over the weekend. It is mounted at a 14.25AOA and the leading edge is about 6 inches off the ground. We are actually going to use roofing shingles for most of the weight. A friend that owns a roofing company is letting us borrow a...

    Static Testing a Wing

    I am looking for some information on the procedure to perform static testing on a wing. The intent is to flip the wing upside down and use a test rig to attach the struts (flying wires actually), then load it up with sandbags. The questions as of now are: Do we need to put it at a high angle of...

    fuel pressure anomoly

    Sender is grounded to the engine which has a cable that runs to the battery. Gauge is grounded to a block on the dash that grounds to the battery also. I'm not real good with understanding the whole ground loop phenomanon and what not but I do know that this is the exact same way the oil...

    fuel pressure anomoly

    The pumps are in series with the electric pump next to the tank 5.5' (4' of 3/8" tube, 18" of 3/8" flexible hose) downstream of the mechanical fuel pump. I flew the plane yesterday for an hour and never had the pressure anomaly. Differences on this flight is that the air was wetter and I had a...

    fuel pressure anomoly

    It would be great to find replacement diagrams - apparently tempest rebuilds them so they must be available - or more likely tempest makes there own. I ruled out gauge as an issue as it reacts as you would expect when the electric fuel pump is switched on during these anomalys. The entire...
